Potain Igo T 70 A
- Max capacity: 8,800 lb (4,000 kg)
- Max tip capacity: 3,200 lb (1,450 kg)
- Max radius: 131 ft (40 m)
- Max height under hook with jib horizontal: 115 ft (35 m)
- Max height under hook with jib at 30˚: 146 ft (44.5 m)
- Variable height mast from 49 ft (15 m) to 115 ft (35 m) with mast inserts.
Chassis: Outriggers swing and lock into position. 14.8 ft (4.5 m) square outrigger spread with an 8.9 ft (2.7 m) slewing radius. Outrigger pads are stowed on the crane during transport (23.6 in x 23.6 in [600 mm x 600 mm]).
Ballast: Ballast requirement for the crane consists of a minimum of 15 slabs, each weighing 4,850 lb (2,200 kg). Additional ballasts are required for different crane configurations.
Optional Ballasting Derrick: Removable and able to be used on other Igo T 70 A units, the hydraulic ballasting derrick uses the hoisting winch and is controlled by the remote control. It can be used to install and remove the ballast slabs.
Mast: Telescoping lattice mast is made vertical by one hydraulic cylinder. Hook heights of 49 ft (15 m), 56 ft (17 m), and 66 ft (20 m) achievable with the standard mast. 360˚ rotation possible during raising sequence.
Mast Inserts: Three 20 ft (6 m) mast inserts available to reach a maximum hook height of 115 ft (35 m). Increasing mast height with one insert provides hook heights of 75 ft (23 m) and 85 ft (26 m); second mast insert provides hook heights of 95 ft (29 m) and 105 ft (32 m); third mast insert provides hook height of 115 ft (35 m).
Jib: 131 ft (40 m) radius standard offsettable lattice jib. The jib can be offset to 30˚. Opening and aligning are carried out automatically by three hydraulic cylinders.
Swing: RVF 151 Optima +: slewing mechanism with a maximum swing speed of 0.8 rpm. Progressive control of the speed with counter-slewing possible, anti-load swinging system makes aligning the load with the jib easier. Multiple rpm speeds possible depending upon parameter selected.
Hoist: 15 LVF 11 Optima: 15 hp variable frequency hoist with 2,425 lb (1.1 t) line pull. 3 notch, progressive speed change according to the accelerating or decelerating ramps. Optima allows the hoist to adapt its speed to the weight of the load.
Trolley: 3 DVF 5: 3 hp variable frequency hoist with 1,102 lb (500 kg) line pull. Three (3) notch winch, progressive speed change according to acceleration or deceleration ramps controlled by the frequency converter.
Reeving: SM/DM block for 2 (SM) or 4-part line (DM). Manual removal of one pin to change between SM and DM. Pure SM1 (section of hook block removed) is possible with a gain of 220 lb (100 kg) lifting capacity.
480 volt, 60 Hz measured at the turntable are recommended for optimal performance. Power supply requirement from city is 19 kVA with the cabin installed, or 32.3 kVA from a generator. Earth rod and electric cable stored on the crane during transport.
Auxiliary remote attached by tethered cord ensures continual operation in case of battery or other malfunction of the wireless remote control.
Optional transport axle sets are available for both jobsite and highway applications. Jobsite axles are rated at either 6 mph (10 km/h) or 15.5 mph (25 km/h); the highway axle set is rated at 50 mph (80 km/h).
